Here's another issue which cropped up when I ran this patch set through
the autobuilder last night - allnoconfig's now fail with:

mm/memory.c: In function 'gate_vma_init':
mm/memory.c:3410:22: error: 'FIXADDR_USER_START' undeclared (first use in this function)
mm/memory.c:3411:20: error: 'FIXADDR_USER_END' undeclared (first use in this function)
mm/memory.c: In function 'in_gate_area_no_mm':
mm/memory.c:3432:15: error: 'FIXADDR_USER_START' undeclared (first use in this function)
mm/memory.c:3432:46: error: 'FIXADDR_USER_END' undeclared (first use in this function)
make[2]: *** [mm/memory.o] Error 1

Any ideas?
